Well, I am guessing by the wagon sized doorway, it might have been an equine level vet – perhaps to care for police and fire service animals. There is a fire station on the same block that is very old, and also the funeral home which dates to the 1800’s and had used horse drawn equipment.

Thats a pure guess – anyone got the Sanborn maps for this hood ? Between 2nd and Cass, its in the Alexandrine alleyway.

Wow, that’s a really interesting building—I wonder what a “veterinary sanatorium” is, anyway? Given that sanatoriums were usually located out in the country, does that mean that this building predates the surrounding neighborhood by a few years?
